United States Patent 6 Claims cl. 229-51 ABSTRACT OF THE DISCLOSURE Atear-up package, especially for food products, such as chocolate, candyand like small articles consists'of' an inner envelope in which theproducts are wrapped and an outer envelope surrounding the innerenvelope. The outer envelope has formed thereon a tear-up portion whichadheres to a portion of the inner envelope, so that when the tear-upportion is torn open, the adhering portion of the inner envelope is alsotorn open and the products wrapped by the inner envelope become exposed.

This invention relates to tear-up packages especially for food productssuch as chocolate, candy and like atticles. The package is of the typein which the products are wrapped into an inner envelope which issurrounded by an outer envelope. In such packages, in order 'to take outsome of the contents of the package, for example some pieces ofchocolate, it is necessary to first open the outer envelope and then topull the inner envelope partly out of the opened outer envelope in orderto be able also to open the inner envelope. The opening of packages ofthe mentioned type accordingly is relatively awkward. Even if an outerenvelope of the tear-up type would be used, the inner envelope wouldstill have to be separately opened, so that opening of the package wouldnot be substantially facilitated.

Accordingly, it is an object of this invention to facilitate opening ofa package in which the packed articles are wrapped in an inner envelopewhich itself is wrapped in an outer envelope. According to theinvention, the outer envelope is formed with a tear-up portion which isfirmly adhering to the portion of the inner envelope situatedimmediately below the tear-up portion, whereby upon tearing away thetear-up portion of the outer envelope, said portion of the innerenvelope situated below the tear-up portion will also be torn open. Inthis manner, when the package is torn open by exertion of a pull on thetear-up portion of the outer envelope, the contents of the innerenvelope will be exposed at the same time and can be taken out of thepackage.

A preferred embodiment of the invention is illustrated in theaccompanying drawings, in which FIGURE 1 is a perspective view of aninterior envelope containing a layer formed by a plurality of smallchocolate tablets arranged to the shape of a usual chocolate square orbar, the outer envelope being shown in dash and dot lines.

FIGURE 2 is a top plan view of a blank of the outer envelope.

FIGURE 3 is a perspective view of the finished package ready for sale.

FIGURE 4 is a similar view after tearing up the package.

Referring to FIGURE 1, a number of single chocolate tablets 1 arearranged to the shape of a one-layer chocolate bar on a rectangularsupporting sheet having a bottom 2 and upturned longitudinal side flaps2a. The tablets 1 together with the supporting sheet 2, 2a are wrappedinto aninner envelope 3 of tin foil. A strip of adhesive 4 extendingover the area of several tablets 1 is applied to 3,389,852 Patented June25, 1968 the .top face of the-tin. foil envelope 3, for example :by anozzle effecting a to-and-fro movement at=the adhesive applying stationof 'any'conventional wrapping machine. Afterwards an external carton 5is wrapped about the-bar consisting of the chocolate tablets 1,the-supporting sheet 2, 2a and the inner envelope 3.

The blank of .the external carton-5 is shown in:.FIG-

I U-RE 2.v This blank comprisesa top part-" and a bottom part 11. Thetop part 10 is connected along-a folding line 15 to a side flap 12, andthis latter is connected along a folding line 14 to a bottom closureflap 14a. The top and bottom parts 10 and 11 are connected toeach otherby a side flap 13 along folding'lines 16 and 17. End flaps 18 and19 areconnected to the top part '10 along folding lines 20 and 21,respectively. 'End closure-flaps 22 and 23 are connected alongfoldinglines 24 and 25 togthe end flaps 18 and 19, respectively.

A tearing portion 6 is formed on the top part 10 of the blank. Thistearing portion starts from the folding line 20 between the top part andthe end flap 18 and is defined by a curved weakening line 7 extendinginwardly from one end of the folding line 20 and across the top 7 part10 to a point 24 adjacent the folding line 15 between the top part 10and the side flap 12, and by a weakening line 8 extending along thefolding line 15 from the other end of the folding line 20 to a point 25intermediate the length of theside flap 12. Between the points 24 and 25of the blank, the material of the blank is out along the line 9, thecutting line 9 slightly passing beyond the folding line 15 in thematerial of the side flap 12. In this manner, when the blank is erectedto form the carton 5, a tearing flap 26 is formed which slightlyprojects laterally beyond the side flap 12 of the carton as will be seenfrom FIGURES 1 and 3.

When the carton blank is wrapped about the inner envelope 3, the tearingportion 6 will be situated above the adhesive strip 4 on the top of theenvelope 3 and will firmly adhere at this region to the portion of theenvelope 3 provided with adhesive.

For opening of the package, the flap 26 is seized with the fingers andthe portion 6 torn open. As illustrated in FIG. 4, when the portion 6 istorn away a portion of the top part 10 of'the envelope 3 adhering to theportion 6 side flaps could be formed as a tearing flap and could be madeto firmly adhere to a corresponding portion of the inner envelope in thefinished package. The connection between the tearing flap and the innerenvelope could also be obtained otherwise than by adhesive, for exampleby tacking or stitching the flap to the inner envelope.

I claim:

1. A tear-up package for food products of the type in which the productsare wrapped in an inner envelope surrounded by an outer envelope, inwhich the outer envelope is formed with a tear-up portion which isfirmly adhering to the portion of the inner envelope situatedimmediately below the. tear-up portion, whereby upon tearing away thetear-up portion of the outer envelope, said portion of the innerenvelope situated below the tearup portion will also be torn away, saidtear-up portion laterally projects beyond said package to facilitate theopening of said package.

2. A tear-up package according to claim 1, in which said tear-up portionis formed at one side of the top portion of the outer envelope and isdefined by a curved weakening line extending from one edge of thepackage across said top portion, and by a weakennig line extending alongan edge of the package.

-A--tear-up package accordingtoclaim 1 ,-in whichsaid tear-up portion isprovided with a projecting flap.
